This is a shrub with stems growing erect or spreading[citation needed] and growing up to 7 feet (2.1 m) in height. The leaves have oval blades up to 7 centimeters long by 4.5 wide[5]: 55774 borne on short petioles.[citation needed] The inflorescence is a cyme of several flowers with tiny white petals and slightly larger white sepals no more than 3 millimeters long. The small winged fruit contains brown seeds.[5]: 55774
This shrub grows in dry or moist forest and shrubland habitat in the Waianae Mountains of Oahu and Nā Pali Coast State Park on Kauai. It is associated with other plants such as koa (Acacia koa), maile (Alyxia stellata), kookoolau (Bidens torta), lama (Diospyros sandwicensis), aalii (Dodonaea viscosa), and naenae (Dubautia plantaginea).[3]
Threats to this rare species and its habitat include introduced plant species, such as mistflower (Ageratina riparia), silk oak (Grevillea robusta), airplant (Kalanchoe pinnata), lantana (Lantana camara), haole koa (Leucaena leucocephala).[3] Feral pigs and feral goats degrade the habitat.[3] Fire, rockslides, and landslides can also damage populations.[2]
